Cloud accelerates business transformation

• Innovate with the latest technology from any source

• Access more types of data, analytics & AI, anywhere

• Improve return on existing investments

Yet to date, less than 20% of enterprise workloads have moved. Why?

Organizations are moving to the cloudbecause it provides AGILITY

• Is quickly understood & adopted• Enhances speed to market• Enables viral adoption of emerging

technologies• Provides solutions for new demands

But the Mainframe ...Organizations are moving to the cloudbecause it provides AGILITY



of digital business

Currently, IBM Z is barely a footnote in this narrative



10


But the Mainframe ...

• Locks important assets in monolithic applications.

• Requires a lot of domain specific knowledge to use.

• Is strongly guarded against broad network access.

• Has a manual and labor intensive approach to resource management and maintenance.

• Has a separate and archaic approach to development and test processes.

• Carries a corporate IT culture which inhibits integration with the rest of the world.

Organizations are moving to the cloudbecause it provides AGILITY



of digital business

Currently, IBM Z is barely a footnote in this narrative

What does it mean to be Agile?

11

1. Liberate existing Intellectual Property assets currently locked in monolithic applications.

2. Provide access to on-premises infrastructure and resources for dev, test, prod.

3. Access and deploy resources via the cloud using modern DevOps methodologies and tools.

4. Recombine the assets based on dynamic business requirements and technology changes.

5. Rinse and Repeat

Goal: Application Development Nirvana

Define a new idea in the morning and have a solution

in production by the end of the day

Future proof your existing IP to easily align with the latest technologies.

What is the competition ?

12

• Docker provides a way of containerizing applications

• Docker Swarm / Kubernetes / ICP / Open Shift proving management layers to running many docker containers

• SCM, CI/CD, test tooling is freely available (and available as docker images)

• Open Source tooling that is freely available that everyone can learn, grow skills (and adopt)

Lets play a little game of pong!

Demo

Not just a game of Pong!

• Front-End• HTML, CSS, Javascript

• Mid-Tier• JAX-RS APIs in Java

• Back-End• Java, COBOL, CICS

DBB:Allows us to either build the whole application ORJust the elements changed by a specific changeset

Create builds under ANY hlq (for personal, test private builds)

19

CICS bundle in git is not a deployable asset but the project that a developermight have been using.

CICS Build toolkit can be used to turn this into a deployable asset.

Wrapping CICS build toolkit as a docker image allows this to be easilycalled from within jenkins

CICS-CI-DEMO is now a provision-able application container that willprovision:

My compiled COBOL load modulesAll the RDO definitions that are neededA WLP JVM Server that contains the deployed java application

Anyone can provision an instance of the application for testing.

25

This running container

Running our image

Using groovy to parse the output from z/OS PT to Extract the names of running containers in case we need to deprovision them later

You appear to have solved it all – can we leave now?

28

• Building the zOS PT image makes the solution immediately live!

• The Jenkins job is responsible for searching for existing containers and cleaning up

• The port number of the provisioned endpoint changes each time

• Rolling updates to instances of applications are not possible

• Application access is not self serve, there’s now online catalog of services a developer can simply pick from

z/OS in your private cloud

z/OS Cloud Broker is technology that gives users the ability to access and deploy z/OS resources and services on Kubernetes based cloud platforms for a seamless and universal cloud development experience

Cloud

Challenge

Client Value

Business critical applications running on z/OS are isolated, and installation of any Cloud platform will not integrate my z/OS subsystem within same control planes. Will require multiple control planes and integration tools.

• z/OS subsystem can be deployed leveraging z/OSMF and standardized Service Broker implementation and Open Service Broker APIs

• Single control plane across z/OS, Linux on Z, x86, Power, and public cloud

• Protect existing investment, optimize management efficiencies, and achieve speed for innovation

32

Centralization and automation of operations to provide z/OS services to agencies or clients in a self-service model.

Providing all types of application developers access to IBM Z environments and resources, leveraging common cloud marketplace open standards and tooling.

DevOps – Attract and exploit new talent and improve time to market

Service Provider – Less burden on Ops in a secure environment

Providing a unified experience for IBM Z cloud services across private cloud and public cloud.

Multi-Cloud Service Integration – Streamline IT investments

Primary z/OS Cloud Broker Use Cases

Phase 3: Redeployment

• Sagar can choose to move a high volume Node.js application from x86 to z/OS

• Build engineer can configure pipeline to rebuild z/OS image for a Node.js application

• Freya can deploy and test a Node.js application on z/OS using a modified Helm chart

Roadmap - vision and where we’re starting

33

Phase 1: Containers for z/OS applications

• Zach can add z/OS nodes for development, test, and production

• Stan can configure templates for z/OS containers

• Bobbi can configure pipeline to build z/OS image

• Alan can deploy and test a CICS COBOL application using a Helm chart

• Richard can use orchestration to move images through to production

Phase 2: Heterogeneous Cluster

• Zach can configure network proxy to publish z/OS-based services to the cluster

• Freya can deploy a Node.js application that uses services deployed by Alan on a z/OS node

• Sagar can architect a solution across Linux on Z and z/OS

• Operations has a single view of the hybrid cluster

Summary

With available, open technologies you can deploy applications in a modern devops style

Kubernetes, has won this iteration of the deployment battle, to stay relevant we have to play our part in heterogenous network deployments

As a platform we are integrating z/OS runtimes into the cloud deployment landscape making it an attractive proposal
